1 round of OA and 2 rounds of VO. OA has two easy LeetCode challenges. During the VO, only research-related questions and fundamental ML questions were asked. ML questions, for example, has 1) given a 2dconv and input, describe the output and kernal dimension of it, 2) any algorithm to evaluate two camera's visual difference.

It was fine but nothing special. Typical questions for an intern applying for an internship program. You wouldn't be surprised. Come with good questions. That always helps. Worst case scenario you don't get it.
